Anyone used star brite marine waxes and sealers?
 

A client of ours uses it on her shower and I was wondering how it would fare on my cars surface?.....I mean they are designed to repel salt water etc etc.

Haven't used it but it shouldn't hurt your paint as long as it has no abrasives in it. Marine abrasives are a lot harsher since the gel coat used it harder than automotive paint.

yeah I kinda figured I mean it's gonna probabaly be wax only not cleaner/wax

Marine waxes and polishes are usually designed specifically for gel coats. I would suggest staying with your traditional car products
